The service end includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.
Example 1:
referring to fig. 1, a flow chart of a control method based on a dual-sided combined touch screen according to an embodiment of the invention is shown. In this embodiment, the control method based on the dual-sided combined touch screen includes:
s1, capturing an outer contact by utilizing a pre-built outer infrared touch matrix, and identifying the outer contact position of the outer contact.
The outer infrared touch matrix is interpreted as an infrared detection network on the surface of the screen according to infrared transmitting and receiving sensing elements arranged on the outer frame of the touch screen far away from the touch screen by utilizing infrared touch technology (Infrared touch control technology). The infrared touch technology refers to the use of infrared transmitting and receiving sensing elements to form an infrared detection network on the surface of a screen, and when an object (such as a finger or a touch pen) in touch operation shields the infrared rays of the infrared detection network, the coordinate position of the touch is further identified, so that the response of the operation is realized. On an infrared touch screen, a circuit board device arranged on four sides of the screen is provided with infrared emission tubes and infrared receiving tubes, and an infrared matrix (infrared detection network) which is intersected transversely and vertically is correspondingly formed.
Further, the embodiment of the invention adopts a bilateral (layer) infrared detection network to realize the control of the touch screen, the outer infrared touch matrix is emitted by an infrared transmitting and receiving sensing element arranged in an outer touch screen outer frame which is far away from the touch screen, and the inner infrared touch matrix is emitted by an infrared transmitting and receiving sensing element arranged in an inner touch screen outer frame which is far away from the touch screen.
It can be appreciated that the assembly distance between the outer touch screen frame and the inner touch screen frame should be determined according to actual needs and production practice, for example: 2mm.
It should be appreciated that the outer contact point refers to a contact point captured by an outer infrared touch matrix, and the outer contact point position refers to a coordinate position of the outer contact point in the outer infrared touch matrix, where the coordinate position may be determined by establishing a planar coordinate system by the outer infrared touch matrix.
In the embodiment of the present invention, capturing an outer contact by using a pre-constructed outer infrared touch matrix, and identifying an outer contact position of the outer contact includes:
judging whether an outer infrared shielding signal exists in the outer infrared touch matrix or not;
if the outer infrared shielding signal does not exist in the outer infrared touch matrix, returning to the step of judging whether the outer infrared shielding signal exists in the outer infrared touch matrix;
If the outer infrared touch matrix has an outer infrared shielding signal, an outer transverse target infrared set and an outer longitudinal target infrared set are extracted from the outer infrared touch matrix according to the outer infrared shielding signal;
determining an outer infrared shielding area according to the outer transverse target infrared set and the outer longitudinal target infrared set;
and extracting an outer shielding central point of the outer infrared shielding area, and taking the outer shielding central point as the outer contact position.
The outer lateral target infrared ray set represents the blocked lateral infrared rays in the outer infrared touch matrix, and the outer longitudinal target infrared ray set refers to the blocked longitudinal infrared rays in the outer infrared touch matrix. The outer infrared shielding area refers to an interaction area of the outer transverse target infrared set and the outer longitudinal target infrared set. The outer shielding center point refers to an image center point of the outer infrared shielding area, for example: when the outer infrared shielding area is square, the outer shielding center point is the intersection point of the diagonal lines of the square.
Further, since the touch operation object (such as a finger or a stylus) has a certain thickness, more than two infrared rays (respectively, a transverse infrared ray and a longitudinal infrared ray) must exist with the outer infrared touch matrix, at this time, all the transverse and longitudinal infrared rays intersecting with the touch operation object need to be extracted from the outer infrared touch matrix, so as to obtain the outer transverse target infrared ray set and the outer longitudinal target infrared ray set.
In the embodiment of the present invention, the determining the outer infrared shielding area according to the outer transverse target infrared set and the outer longitudinal target infrared set includes:
extracting a transverse target infrared edge line pair in the outer transverse target infrared ray set, and extracting a longitudinal target infrared edge line pair in the outer longitudinal target infrared ray set;
and identifying the interactive areas of the transverse target infrared edge line pair and the longitudinal target infrared edge line pair, and taking the interactive areas as the outer infrared shielding areas.
The pair of lateral target infrared rays may be explained as the edge lines on both sides of the outer lateral target infrared ray set, and the pair of longitudinal target infrared rays may be explained as the edge lines on both sides of the outer longitudinal target infrared ray set. The interaction area refers to an area surrounded by the transverse target infrared edge pair and the longitudinal target infrared edge pair.

The inner infrared touch matrix refers to an infrared detection network emitted by an infrared emitting and receiving sensing element in an outer frame of the inner touch screen. The inner contact prediction area refers to an area where a contact of an object in touch operation may exist in the inner infrared touch matrix. The inner contact position refers to the position of an inner infrared touch matrix of a contact of an object in touch operation.
It will be appreciated that the determination time of the inner contact position can be greatly saved by the definition of the inner contact prediction area. The time for determining the contact far lower than the outer contact is shortened, and the area for scanning and judging the position of the inner contact is reduced from the original touch screen area to the inner contact prediction area.
In detail, referring to fig. 2, the defining the inner-side contact prediction area in the pre-constructed inner-side infrared touch matrix according to the outer-side contact position includes:

s22, identifying the association vertical line and the association vertical point of the inner-edge infrared touch matrix;
s23, defining an inner edge contact prediction area in the inner edge infrared touch matrix according to a preset inner edge prediction radius and the associated vertical point.
The associated vertical line can be interpreted to mean the vertical line of the plane where the inner infrared touch matrix is located, which is drawn through the outer contact position. The radius of the inner edge contact prediction area is preset by the inner edge prediction radius, and can be determined according to the distance between the outer frame of the touch screen and the touch screen, for example: 1cm. The inner contact prediction area refers to a circular area with a radius equal to the inner prediction radius.
In detail, referring to fig. 3, the defining an inner contact prediction area in the inner infrared touch matrix according to the preset inner prediction radius and the associated vertical point includes:

extracting an inner edge prediction infrared ray set intersected with the inner edge contact prediction area from the inner edge infrared touch matrix;
shielding monitoring is carried out on the inner-side prediction infrared ray set, and whether an inner-side infrared shielding signal exists in the inner-side infrared touch matrix or not is judged;
if the inner infrared touch matrix does not have the inner infrared shielding signal, returning to the step of shielding and monitoring the inner predicted infrared set;
if the inner infrared touch matrix stores an inner infrared shielding signal, extracting an inner transverse target infrared set and an inner longitudinal target infrared set from the inner predicted infrared set according to the inner infrared shielding signal;
Determining an inner infrared shielding area according to the inner transverse target infrared set and the inner longitudinal target infrared set;
and extracting an inner shielding central point of the inner infrared shielding area, and taking the inner shielding central point as the inner contact position.
Further, the inner edge prediction infrared ray set refers to infrared rays which are emitted by an infrared emission tube and an infrared receiving tube in the outer frame of the touch screen and intersect with the inner edge contact prediction area, and the infrared rays comprise transverse infrared rays and longitudinal infrared rays. The inner side transverse target infrared ray set refers to transverse infrared rays intersecting the inner side contact prediction area in the inner side infrared touch matrix. The inner-side longitudinal target infrared ray set refers to longitudinal infrared rays intersecting the inner-side contact prediction area in the inner-side infrared touch matrix.
And S3, calculating a touch instruction vector according to the outer edge contact position and the inner edge contact position, and calculating an optimal touch panel regulation angle according to the touch instruction vector.
The touch instruction vector is a vector formed by connecting the outer contact position and the inner contact position, and the direction of the touch instruction vector points to the outer contact position from the inner contact position. The optimal touch panel regulation angle refers to an optimal angle required to be regulated and controlled by the touch screen under the current angle.
In the embodiment of the present invention, the calculating the touch command vector according to the outer edge contact position and the inner edge contact position includes:
constructing a touch instruction space coordinate system according to the outer infrared touch matrix and the inner infrared touch matrix;
respectively identifying the outer side space contact position and the inner side space contact position corresponding to the outer side contact position and the inner side contact position in the touch instruction space coordinate system;
and calculating the touch instruction vector according to the outer edge space contact position and the inner edge space contact position by utilizing a pre-constructed touch vector formula.
In the embodiment of the present invention, the following is the following formula according to the touch vector formula:
wherein,representing touch instruction vectors, l out Representing the outer spatial contact position, l in Representing the position of the inner side space contact point, x in Representing the coordinates of the inner side space contact position in the x-axis direction, x out Representing the coordinates of the outer spatial contact position in the x-axis direction, y in Representing the coordinates of the inner side space contact position in the y-axis direction, y out Representing the coordinate of the outer space contact position in the y-axis direction, z in Representing the coordinates of the inner edge space contact position in the z-axis direction, z out Representing the coordinates of the outer spatial contact position in the z-axis direction,/- >Unit vector representing x-axis, +.>Unit vector representing y-axis, +.>Representing a unit vector of the z-axis.
In the embodiment of the present invention, the calculating the optimal touch panel adjustment angle according to the touch instruction vector includes:
acquiring a current panel plane where the inner-edge infrared touch matrix is located;
acquiring a panel projection line segment of the touch instruction vector on the plane of the current panel;
determining a current panel angle according to the panel projection line segment and the touch instruction vector;
calculating the optimal touch panel regulation angle by utilizing the current panel angle and a preset optimal panel angle according to a preset angle regulation formula, wherein the angle regulation formula is as follows:
θ′＝θ best -θ now
wherein, theta' represents the optimal control angle of the touch panel, and theta best Represents the optimal panel angle, theta now Representing the current panel angle.
The current panel plane refers to the plane where the current display screen or touch screen is located. The panel projection line segment refers to an included angle between the panel projection line segment and the touch instruction vector, and an acute angle is formed. The optimal panel angle refers to the most suitable angle that matches the current user writing angle.
It can be understood that, because the position of the plane where the user who sends the touch action and the touch screen are likely to have a poor writing angle (for example, when the user reports by using the touch panel, the user faces the audience and needs to write, and the user cannot move the position at will or can not block the sight of the audience), the aim of achieving the optimal writing angle is achieved by automatically adjusting the angle of the touch panel. The intersecting writing angle can be caused by the writing environment, and the aim of correcting bad use habits of users is fulfilled by actively adjusting the angle of the touch panel to the optimal panel angle. For example: children or persons using the infrared touch screen for a long time can cause writing fatigue if a poor writing angle is used for a long time and the children or persons do not find themselves.
And S4, adjusting the angle of the pre-constructed touch panel according to the optimal touch panel adjusting angle and judging whether a user adjusting instruction is received or not.
And if a user regulation instruction is received, executing S5, and regulating and controlling the angle of the touch panel according to the user regulation instruction.
And if the user regulation instruction is not received, executing S6, and regulating the touch panel according to the optimal touch panel regulation angle.
It can be explained that in the process of adjusting and controlling the angle of the touch panel, the user may have a writing requirement that has reached the user, and the user does not need to continuously adjust to the optimal writing angle at this time, so that the user can issue a pause instruction at any time, and if the user does not issue the pause instruction all the time, the control panel is adjusted and controlled all the time to the optimal panel angle.
Compared with the problems in the prior art, the embodiment of the invention determines the touch instruction vector through the inner infrared touch matrix of the outer infrared touch matrix, then realizes the purpose of regulating and controlling the touch panel according to the touch instruction vector, captures the outer contact by using the pre-built outer infrared touch matrix before obtaining the touch instruction vector, recognizes the outer contact position of the outer contact, obtains the touch information of the outer edge at the moment, realizes the calculation of the touch instruction vector by obtaining the inner contact position, and firstly defines the inner contact prediction area in the pre-built inner infrared touch matrix according to the outer contact position in order to improve the efficiency, then captures the inner contact position of the inner contact according to the inner contact prediction area and the inner infrared touch matrix, and when obtaining the touch instruction vector, calculates the optimal touch panel angle according to the touch instruction vector, thereby realizing the purpose of regulating and controlling the angle of the pre-built touch panel according to the optimal touch panel, and judging whether a user needs to receive a regulation and control instruction in a touch panel or not in a regulation process, so that the user needs to regulate and control instruction can be reached; if a user regulation instruction is received, regulating and controlling the angle of the touch panel according to the user regulation instruction; and if the user regulation and control instruction is not received, regulating and controlling the touch panel according to the optimal touch panel regulation and control angle. Therefore, the control method, the control system, the electronic equipment and the computer readable storage medium based on the bilateral combined touch screen mainly aim to solve the problems of poor flexibility and low user satisfaction in the current infrared touch technology.
